Jenna-Louise Coleman: 'Doctor Who debut is unique, surprising'

New Doctor Who companion Jenna-Louise Coleman has said that her character will "surprise" fans with a never-before-seen introduction.

The Waterloo Road actress was last month confirmed to be starring alongside Matt Smith in series seven of the BBC sci-fi, replacing Karen Gillan and Arthur Darvill.

Speaking about the upcoming debut, Coleman told viewers to expect "lots of secrets and intrigue" from her alter ego.

"I know what my introduction is," she told Doctor Who Magazine. "And I have a general idea of where we're going to go. There's definitely a story arc.

"It sounds really interesting, really exciting. I don't think anything's been done like it before, but there are lots of secrets and intrigue, and I think it's going to throw and confuse a lot of people, and surprise a lot of people."
